Runner Nicole Teeny wants to do something possibly absurd: race an ultramarathon against a horse. It all started with a theory and a diagnosis.

In GIRL v. HORSE, a four-part podcast from 30 for 30 Podcasts, Teeny comes to terms with being diagnosed with epilepsy, and hating the loss of control, decides to push her body to the limit.

In the process, she investigates how evolution drove humans to become runners—and what horses have to do with it—all while training to beat a steed and settle the battle between mind versus body and girl versus horse.

Who will win?
